error when creating yolov3 architecture

[JDM559]

Describe the bug I was following your steps but this error popped up when i was trying to create the yolov3 architecture

To Reproduce Code and steps to reproduce the behavior:

remotes::install_github("maju116/platypus")
install.packages("keras")
install.packages("tensorflow")
library(tidyverse)
library(platypus)
library(abind)
library(keras)
library(tensorflow)


test_yolo <- yolo3(
  net_h = 416, # Input image height. Must be divisible by 32
  net_w = 416, # Input image width. Must be divisible by 32
  grayscale = FALSE, # Should images be loaded as grayscale or RGB
  n_class = 80, # Number of object classes (80 for COCO dataset)
  anchors = coco_anchors # Anchor boxes
)

Expected behavior A clear and concise description of what you expected to happen.
